Washburn doesnt make the WG587 anymore, Musiconetwothree is still selling them from their own large stock of them. (At least thats what I hear)
However, Washburn IS currently making a 7 string, the X17. Its basically a WG587 with a basswood (rather than alder) body, offset dots, string thru, and an update to Washburn's usual goofy headstock, which looks wierd this large imo. The price is the same at $200. Check it:
I played this guitar in Sam Ash a few weaks ago, and it was impressive for the price. The neck was pretty thin, and very playable. The frets werent the best, and the rosewood end was pretty nasty, but eh, get what you pay for.
I adjusted to it instantly, and overall I liked it, but If I were to get one(a 7), I'd have to grab the WG587, as Im an alder freak, plus it has a 5 way.
Either way you look at, you now have a choice if you go the cheap Washburn route. The sweet offset dots are killing me, but alder is the best! And who doesnt like a Ibanez headstock ripoff
